Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel beam-column joint reinforcement installation structure. Background Technology

[0002] As people have increasingly higher requirements for indoor space, higher demands are also being placed on structural design. Large conference centers, hospitals, and other facilities are using steel beams and columns as the main load-bearing components in some large-span or large-space areas to maximize usable space. This reduces the cross-section of the main components while maintaining the original load-bearing capacity, thus increasing usable space. Compared to reinforced concrete structures, steel structures face significantly greater construction difficulties at critical locations such as beam-column joint reinforcement binding. The large number of reinforcing bars and excessive density can easily lead to problems such as honeycombing and pitting in steel-concrete structures. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a steel beam-column joint reinforcement installation structure, which optimizes the reinforcement layout, reduces the construction difficulty, and avoids problems such as honeycomb and pitting in steel-concrete structures caused by excessive reinforcement.

[0004] To achieve the above technical effects, this utility model provides a steel beam-column joint reinforcement installation structure, which includes:

[0005] The steel-concrete composite column and the steel beam, wherein the steel beam includes multiple rows of beam reinforcement arranged in parallel and fixedly connected to the steel-concrete composite column, the connection end of the bottom reinforcement of the steel beam and the steel-concrete composite column is bent towards the side relatively away from the bottom two rows of beam reinforcement and forms a haunch, a reserved space is formed between the haunch and the bottom two rows of beam reinforcement, and an equal strength connecting plate is fixedly connected between the bottom two rows of beam reinforcement and the steel-concrete composite column within the reserved space.

[0006] Preferably, a stiffening plate is fixedly connected between the equal-strength connecting plate and the steel-concrete column.

[0007] Preferably, the steel beam is provided with a reinforcement auxiliary positioning component, which includes a positioning frame and multiple support plates fixedly connected to the positioning frame and used to support the bottom of the beam reinforcement. The multiple support plates are arranged one-to-one with multiple rows of beam reinforcement.

[0008] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0009] 1) By adopting equal-strength connection plates and steel reinforcement auxiliary positioning components, the installation efficiency of steel reinforcement at the beam-column joint of the steel structure is improved. Under the premise of ensuring that the original stress result of the structure remains unchanged, the construction process is optimized and the problems of high construction difficulty and slow speed of steel beam-column joint are solved.

[0010] 2) It solves common quality problems in traditional steel structure beams, such as messy installation of bottom reinforcement bars and excessively dense reinforcement spacing leading to honeycomb and pitted surfaces after concrete pouring, effectively ensuring the quality of subsequent concrete structure forming.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6 As shown, this utility model embodiment provides a steel beam-column joint reinforcement installation structure, including a steel-concrete column 1 and a steel beam 2. The steel beam 2 includes multiple rows of beam reinforcement 4 arranged in parallel and fixedly connected to the steel-concrete column 1. The connection end of the bottom reinforcement 42 of the steel beam 2 and the steel-concrete column 1 is bent towards the side relatively away from the bottom two rows of reinforcement 41 of the steel beam 2 to form a haunch 21. A reserved space 7 is formed between the haunch 21 and the bottom two rows of reinforcement 41, and an equal strength connecting plate 3 is fixedly connected between the bottom two rows of reinforcement 41 and the steel-concrete column 1 within the reserved space 7.

[0022] Furthermore, in this embodiment, a stiffening plate 5 is fixedly connected between the equal strength connection plate 3 and the steel-concrete column 1. The equal strength connection plate 3 is made of steel plate, and the stiffening plate 5 is made of triangular steel plate and is welded to the equal strength connection plate 3. The equal strength connection plate 3 is welded to the second row of reinforcing bars 41 at the bottom of the beam. The haunch 21 is also connected to the steel-concrete column 1 by welding. By adopting the haunch structure, the space for the arrangement of reinforcing bars in the beam-column connection area is increased. The use of the equal strength connection plate 3 for the second row of reinforcing bars 41 at the bottom of the beam increases the convenience of reinforcing bar construction.

[0023] Furthermore, in this embodiment, the steel beam 2 is provided with a steel bar auxiliary positioning component 6. The steel bar auxiliary positioning component 6 includes a positioning frame 61 and multiple support plates 62 fixedly connected to the positioning frame 61 and used to support the bottom of the beam steel bars 4. The multiple support plates 62 are arranged one-to-one with multiple rows of beam steel bars 4. The support plates 62 are fixed to the positioning frame 61 by pin plates 63. The size of the positioning frame 61 is determined according to the beam width, and the positioning spacing is determined by calculation.

[0024] The specific construction steps for the steel beam-column joint reinforcement installation structure of this utility model embodiment are as follows:

[0025] Steel column and beam installation and connection → steel column reinforcement binding to the top of the column → steel column formwork installation → steel column concrete pouring to the design position → beam formwork installation → installation of auxiliary positioning components for steel beam reinforcement → installation of bottom reinforcement of core area beam → installation of second row of bottom reinforcement of core area beam → installation of reinforcement pads → removal of auxiliary positioning components for reinforcement.

[0026] It should be noted that during the installation of the steel column formwork, a separate formwork is used within 0.9m below the pouring height. When the column formwork is removed, the formwork in this area is retained to facilitate the subsequent installation of the beam formwork. The column formwork is installed 1cm to 2cm higher than the pouring surface elevation. Before pouring the concrete for the steel column, the pouring height of the steel column concrete is determined according to the bottom elevation of the welding position of the bottom reinforcement of the beam. The positioning pin plates are removed in advance, and the support plate is fixed to the positioning frame with pins. Taking the bottom of this project with two rows of reinforcement as an example, the installation process is as follows: During installation, install from top to bottom, with the bottom open area facing downwards. After installation, first install the first support plate, then install the second support plate. After the positioning parts are firmly fixed to the steel beam structure by the two support plates, install the bottom support plate, and then install the bottom row of reinforcement. To prevent the reinforcement from slipping, after the reinforcement is placed in place, the reinforcement is temporarily fixed to the support plate with tie wire. Then, the bottom row of reinforcement is welded to the steel column.

[0027] After the bottom reinforcement is installed and fixed, the second row of reinforcement is installed. The procedure is the same as that for the bottom reinforcement. For ease of operation, the second row of reinforcement is welded to the steel column through a plate of equal strength. After the bottom reinforcement of the beam is installed, the bottom reinforcement and the second row of reinforcement are separated by shims. The shims are made of steel reinforcement. After the shims are installed and fixed firmly, the positioning parts are removed. The removal sequence is the reverse of the installation sequence.

[0028] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
